Ross Ulbricht is the infamous developer and owner of the Silk Road darknet market. Silk Road was a black market, used primarily for trading illegal goods, such as drugs and firearms. The users' anonymity was ensured by the use of the Tor protocol for accessing the website, and Bitcoin for conducting transactions. FBI has managed to confirm Ulbricht's identity as the founder in 2013, and after the service was shut down, he was charged with several felonies and sentenced to life in prison.
